To all whom-it may concern: 7

Be it known that I, HENRY F. BnoHMAN, a Citizen of the United States, residing at Battle Creek, in the county of Calhoun" and State of Michigan, have invented certain new and useful Improvements in Inking Mechanism for Printing-Presses and I hereby declare that the following is a full, clear, and exact description thereof, reference be ing had to the accompanying drawings, which form part of this specificationQ This invention relates toprinting presses and has particular reference to the inking mechanism thereof; and is' especially designed for use withso called rotary presses,

but is also adapted to other types of presses wherein a very fine and uniform distribu tion of ink is desired.

The object of the invention is to provide a primary distribution of the ink after it is taken from the fountain and before it is delivered to the distributing drum or system of distributing rollers; and to accomplish this I provide a distributing table between the ink fountain and the drum and a reciprocating ductor, or ductors, to take ink from the fountain and deliver it to the table and primarily distribute the ink thereon before the ink is delivered to the drum; so that instead of the drum receiving the ink in daubs from a line on the periphery of the ductor, it receives it practically uniformly distributed upon the periphery of the ductor. Preferably I employ two ductors, one of which takes ink from the fountain and supplies it to and distributes it on the table as stated, and the other of which assists in distributing the ink on the table and also delivers it from the table to the ink drum. The essentially novel feature of the invention is the provision of a distributing table between the ink fountain and the ink drum.

In the accompanying drawings I have illustrated one embodiment of the invention as applied to the inking mechanism of a rotary press, and will explain the invention in connection therewith to enable others skilled in the art to adapt and use the same; but I do not consider the invention restricted to the particular construction or arrangement of parts shown, and refer to the claims for concise definitions of the novel invention for which protection is desired.

The accompanying drawing represents a diagrammatical sectional elevation of a rotary printing couple and inking mechanism therefor equipped with the invention.

In said. drawings 1 designates a platecylinder; 2 the impression cylinder; 3 theform rollers; 3 the intermediate rollers taking inkfrom the distributing rollers l which receive ink from the drum 4- in the usual manner; and rt rare distributing rollers or vibrators arranged to contact with the periphery-of the drum 4 and disseminate the .1nk thereon in the usual manner.

ink fountain. All the aforesaid parts may be of the usual or any preferred construction and will be readily understood by pressmem Intermediate the fountain 6 and the drum 4:, 1s a primary distributing table 5. Oper- 6 is the.

ating upon the table 5 and between the drum I 4 and fountain 6 is a reciprocating ductor roller or rollers, two preferably being used.

These ductor rollers 7 and 8 are designed and adapted to be rolled back and forth over the table 5 and between the drum at and fountain 6 by any suitable means (not shown) such as may be preferred by the designer and best suits the general arrangement or construction of the press with which the invention is used.

In the example shown the ductor roller 7 is adapted to take ink from the fountain roll 6 and supply it to the table 5 and to also cut up or distribute the ink on said table 5 as the ductor rolls thereover. The ductor roller 8 preferably travels with the roller 7, and assists in distributing the ink on table 5, and also transfers ink from the table 5 to the drum 4.

It will be seen that with such construction and arrangement of parts the ink taken from the fountain 6 will be primarily distributed on the table 5, and will be practically uniformly applied to and around the periphery of the ductor roller 8 before the latter contacts with the drum 4:; consequently when the drum 4 contacts with ductor 8 it receives ink therefrom in a substantially uniformly distributed condition; and such ink is thereafter more easily quickly and thoroughly disseminated on the surface of the drum by the vibrators P before it is taken from the drum by the rollers i As a result of this manner of supplying By using this invention a superior ink.

distribution can be producedwith the same. number of rolls than has hitherto been possible; or as good distribution of ink can be obtained With a less number ofrolls than has been hitherto possible. The invention is particularly useful .for fine press Work Where it is essential that the ink shall be most thoroughly and uniformly distributed before it is applied to the form rollers.

What. I claim is:

1. Inking mechanism for printing presses, comprisingan ink drum and co-acting'roll ers, an ink supply, an ink distributing table intermediate the fountain and drum, and two reciprocating ductor rollers respectively adapted to take ink. from the fountain and Copies of this, patent may be obtained; for

supply and delivering it to the table, and

the otherducton roller deliveringink. from.

the table to the distributing means;

3. In inking mechanism for printing pressesthe combination of an ink drum and co-acting distributing rollers; an ink fountain, a distributing table intermediate the fountain and the drum, a pair of recipro- Gating ductor; rollers adapteol to operate upon said table between the fountain and the drum, one of the ductor rollers, taking 7 ink from the fountain and delivering? it to thetalble, and theother .ductor delivering ink from the: tableto; the drum.

4; In inking apparatusv for printing presses, the combination, of a set of distributingirol lers,a" fountain, a talble intermediate the fountain and distributing rollers,.andi pair of reciprocating ductorrollers one of which takes ink from. the fountain and the. other delivers it to the distributing rollers,

both: said ductors distributing ink upon the said table.

In testimony. that I claim. the foregoing as my own, I aflix my signature,
